Because the mist particles produced by the ultrasonic nebulizer are large and the atomization is fast, the patient inhales too much water vapor, which humidifies the respiratory tract, and the dry and thick secretions in the respiratory tract that partially blocked the bronchi absorb water and expand after absorbing water, increasing the resistance of the respiratory tract. Hypoxia may occur, and the ultrasonic nebulizer will cause the liquid medicine to form drops of water and hang on the wall of the inner cavity, which is not effective for lower respiratory diseases, and the demand for medicine is large, resulting in waste. The composition of the utility model includes : a liquid medicine chamber ( 1 ), the liquid medicine chamber is connected with the aerosol generator ( 4 ), the aerosol generator is connected with the atomization medicine chamber ( 2 ), the The aerosol generator is connected with the frequency controller. The utility model is used for the atomization of medicinal liquid.

Description

Nebulizer for mechanical ventilation

Technical field:

The utility model relates to a special atomizer for mechanical ventilation.

Background technique:

Medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli, and chest cavity. Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lung deposition through inhalation, so as to achieve painless , The purpose of rapid and effective treatment. Existing nebulizers are mainly ultrasonic nebulizers.

The nebulizer of the ultrasonic nebulizer is non-selective to the mist particles, so most of the drug particles produced can only be deposited in the upper respiratory tract such as the mouth and throat, and due to the small amount of deposition in the lungs, it cannot effectively treat lower respiratory tract diseases. At the same time, because the fog particles produced by the ultrasonic nebulizer are large and atomized quickly, the patient inhales too much water vapor, which humidifies the respiratory tract. Resistance may cause hypoxia, and the ultrasonic nebulizer will cause the liquid medicine to form water droplets and hang on the inner cavity wall, which is not effective for lower respiratory diseases, and the demand for medicine is large, resulting in waste.
